hussa20431 Hi to switch off recurring goodybags (or auto top up) you have to go to your payments page.
This is found by clicking on account at the top of your dashboard page and then on payments from the drop-down menu.
At or close to the top of the payments page you will find the payment method section.
You can click on the blue text to change your recurring goodybags or auto top up.
Unless you are leaving giffgaff or are no longer wanting to use your bank/credit card you won’t have to remove the card details.
If you have done these things and the page hasn’t reflected the changes try logging off and back on again and go back to payments and check again
